> ACPI: INT_SRC_OVR (bus 0 bus_irq 9 global_irq 9 dfl dfl) > NR Log Phy Mask Trig IRR Pol Stat Dest Deli Vect: > 09 003 03 0 1 0 1 0 1 1 71 Looks like we're setting up IRQ9 correctly -- level/low -- which is what default/default is. Other systems break if dfl/dfl is not interpreted as level/low. > 9: 100000 0 IO-APIC-level acpi But ACPI (alone on the IRQ) is getting an interrupt storm -- IRQ9 is low and ACPI doesn't know why. Please verify that you've got the latest BIOS for this box, and send along 1. /proc/interrupts and demsg from booting same kernel with "acpi=off" 2. output from dmidecode available in /usr/sbin/, or here: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/utils/ i'll send a patch later to force IRQ9 to level/high -- for if the ACPI interrupt works properly with that setting, then we know we've mis-interpreted what we think should be dfl/dfl on this box. thanks, -Len - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ | ||||||||||||
